Ed - Can't believe it's been 10 years since the Genealogical Congress at Trinity. I still remember the difficulties of getting there since it was right after 9/11 and the incredible kindness of the Irish people once they heard our American accents. First thing I'd suggest is taking their short orientation class - it explains about copy cards, etc. Saves you time in the long run. And think about getting a pass from the front desk to use the cafeteria across the square in the headquarters building - good food at reasonable prices. Although I always begrudge the extra time to walk over there and back, giving up valuable research time. Once you're ensconced down on the 2nd level of the basement of the Family History Library, you should check out the set of field and house books done as part of the Primary Valuation. On their card catalog, do a title search under Valuation Books. Several entries will appear but you want the one shown as "Valuation Books Great Britain, Office of General Valuation of Ireland." Finding the one for the location you want can be a challenge (there are 355 rolls of film in the set). The film notes are organized first by type - Quarto, Tenure, House and Field. Within each category, they are arranged alphabetically by County and then somewhat by barony. Some include the names of the civil parishes on the roll but a lot don't so you may have to pull several rolls to get what you want. The last time I was at the FHL, these rolls were being kept off site and if they still are, you'll need to order them to be delivered the next day or so. It means being organized which is something I'm not. But once you find the right book, there is the physical description of your family's buildings, dimensions and materials, as well as information about the leases, etc. I found the only reference in Ireland to one family in a field book because they left for America after the field book was prepared but before the final Griffith Valuation was printed. When I can't read any more film for awhile, I wander over the actual books in the Irish section. There's always something interesting to find there. If you're going to use the field and land books, you might want to read though James Reilly's book "Richard Griffith and His Valuations of Ireland." Another set of films to think about would be the Registry of Deeds. It's unlikely that your family ever registered a deed but you can read about their landlord's various transactions and your family's townland might be mentioned, or even your family, although that's pretty improbable. The official title in the catalog is "Transcripts of memorials of deeds, conveyances and wills, 1708-1929". There are indexes by place names and by grantors and grantees which you really need since there are 2,580 rolls of film in the set. I found the transaction where my family's landlord received the land from his father in exchange for giving up other land so his brother could give that land as part of a marriage settlement. Gives you a better idea of how the moneyed classes worked. Have a great time. Theresa Liewer
